Abstract. Although tsunamis generated by submarine mass failure are not as common as those induced by submarine earthquakes, sometimes the generated tsunamis are higher than a seismic tsunami in the area close to the tsunami source, and the forecast is much more difficult. In the present study, reciprocal Green's functions are proposed as a useful tool in the forecast of submarine landslide tsunamis. The forcing of the continuity equation due to depth change in a landslide is represented by the temporal derivative of the water depth. After a convolution with the reciprocal Green's function, the tsunami waveform can be obtained promptly. Thus, various tsunami scenarios can be considered once a submarine landslide happens, and a useful forecast can be formulated. When a submarine landslide occurs, the various possibilities for tsunami generation can be analyzed, and a useful forecast can be devised.

Short summary
Tsunamis generated by submarine landslide was considered rare. However, more and more studies indicate many tsunami events can be attributed to submarine landslides. At the same time, knowledge and experience has been accumulated in simulating this kind of tsunami. We believe it is time to think about the forecast of this kind of tsunami, and the approach we use is very helpful in building a feasible forecast system for submarine landslide tsunami.
